Now i don't follow the amiga demo scene in detail but i have been thinking the last years how boring the sound is on new Amiga demos... i mean technically... no one was really pushing the sound hardware and mostly use standard protracker MODs.

I guess the ST demo scene is more motivatd to push the weak sound of the ST soundchip ;) There have been some amazing new sounds for the ST thru the years and thanks to maxymiser most scene musicians are using the new timer effects in a great way and still exploring new ST sounds.

Anyway good to see (and hear) some new Amiga sounds that works on an non-accelerated 500. This is what makes the demo scene so great.

Beside the work from Oxygene I think there were very sophisticated, if not revolutionary developments to address the specifics of the Amiga 500 during the past years. Some examples that come to mind:
Virgill's amazing Amigaklang (and Atariklang, thankfully) or Hoffman's approaches to squeeze music in a demo as described here:

Also worth mentioning are the recent developments and improvements around Pretracker and recently Protracker.

and you can add AHX, that is very different from classic Paula's protracker

I'm on the Pretracker bandwagon, so lovely sounds coming out of that one :)

I did not know about Pretracker, seems to be made by the same guys who did AHX... So it is a kind of successor to AHX?

I terms of Amiga audio tech, there's also Platon's UNZ music engine that you can hear at the very end of Bacon of Hope - I believe this uses blitter techniques as well as other innovations. He writes it up at the end of https://dump.platon42.de/bacon/

That was impressive... 12 channels is not common for Amiga demos AFAIK, i wonder how that DSP effect is achived?

I do rememeber a thread at Atari-Forum that discussed using the ST BLiTTER for sound.

Stefan Lindberg: Indeed, I wondered the same when listening to Virgill's and Platon42's compo entry for Gerp 2026: https://demozoo.org/music/385484/
